作者： zou cainengt tao shizhen research institute of petroleum exploration and development PetroChina Beijing 100083 China

Marine carbonate oil and gas fields have become an important exploration area in china and even across the world. Their formation, distribution and enrichment are special owing to the complexity of the deposition, diagenesis and accumulation, which is caused by the multiplicity of the carbonate depositional environments and facies, huge extensions of formation time and burial depth, complication of diagenetic evolution, heterogeneity as well as the development of pores, caves and fractures affected by various factors. Oil and gas accumulations in carbonate rocks are not strictly controlled by the second-order structure belt. Most of them, under certain structural settings, are controlled by sedimentary diagenesis and its favorable facies. The hydrocarbon reservoir type is predominantly stratigraphic. Based on the worldwide researches of carbonate fields, the paper concludes that 7 main factors control the formation and distribution of middle-large marine carbonate stratigraphic fields.

Energy is the basis of human development and the impetus of society progress. There are three sources of energy: energy of celestial body outside the Earth, the Earth energy and energy of interaction between the Earth and other celestial bodies. Meanwhile, there are three scales of co-evolution: the evolution of the Sun-Earth-Moon system on an ultra-long time scale has provided energy sources and extra-terrestrial environmental conditions for the formation of the Earth system;the evolution of the Earth system on a long time scale has provided the material preconditions such as energy resources and suitable sphere environment for life birth and the human development;on a short time scale, the development of human civilization makes the human circle break through the Earth system, expanding the extraterrestrial civilization. With the co-evolution, there are three processes in the carbon cycle: inorganic carbon cycle, short-term organic carbon cycle and long-term organic carbon cycle, which records human immoderate utilization of fossil energy and global sphere reforming activities, breaking the natural balance and closed-loop path of the carbon cycle of the Earth, causing the increase of greenhouse gases and global climate change, affecting human happiness and development. The energy transition is inevitable, and carbon neutrality must be realized. Building the green energy community is a fundamental measure to create the new energy system under carbon neutrality target. china is speeding up its energy revolution and developing a powerful energy nation. It is necessary to secure the cornerstone of the supply of fossil energy and forge a strong growing pole for green and sustainable development of new energy. china energy production and consumption structure will make a revolutionary transformation from the type of fossil energy domination to the type of new energy domination, depending on a high-level self-reliance of science and technology and a high-quality green en

近废型稠油油藏难以通过常规开发方式有效动用剩余储量,火驱技术为此类油藏进一步提高采收率提供方向。现阶段,火驱技术已趋于成熟,但由于成本投入大、经济性差,火驱技术的推广应用面临困境。通过引入量本利分析法中的盈亏平衡模型和敏感性分析,从多维度的经营视角,揭示不同油价年产油量和成本的平衡关系,明确影响火驱经济性的关键指标,进而推动生产运行优化和决策效能提升。研究结果表明,由于储层前后认识差距大,投入力度大于产出力度,同时管控方向不明确,导致火驱成本有效性低,持续开发经营风险认识不足,影响油藏开发投入决策。研究结果为火驱的经营效益提升指明方向,也为近废型稠油油藏效益开发提供管理新思路。
